The EDCO QC2B-SC-0030 is a 3-pack of 30-grit double diamond Dyma-Dots for the Magna-Trap line of floor grinders, bonded for soft or abrasive concrete. The aggressive 30-grit double-diamond segments strip epoxy, mastic, thinset, and waterproofing coatings quickly while leaving a smooth surface with minimal scratching and no gouging. Concrete contractors and surface-prep crews choose the soft-concrete (yellow) bond for green or coastal slabs where a harder bond would glaze over.
Use Cases
- Removing epoxy, mastic, thinset, and waterproofing coatings from concrete floors.
- Surface prep on soft, green, or coastal-area concrete that needs a harder diamond bond.
- Aggressive grinding passes where 30-grit double dots cut faster than single dots.
- Coating removal and floor leveling ahead of new flooring or sealer.

Frequently Asked Questions
What does the 30-grit Dyma-Dot do?
The coarse 30-grit double diamonds aggressively strip coatings like epoxy, mastic, and thinset and grind down high spots, leaving a smooth surface with minimal scratching.
Why choose the soft-concrete bond?
On soft, green, or coastal-area concrete a softer (yellow) bond exposes fresh diamond faster so the dots keep cutting instead of glazing over. Harder concrete uses a medium or hard bond instead.
How many come in a pack?
This is a 3-pack of double Dyma-Dots, the set that fits the Magna-Trap grinder head.
What grinder does it fit?
